Description

本発明は、エアバッグを車両に固定する固定装置に関し、特に、自動車用のエアバッグ用のガス生成器が、少なくとも１個の固定ボルトとそれにねじ結合されるナットの手段により固定され、前記固定ボルトは、ガス生成器用で、前記エアバッグを搭載し自動車部品に固定する保持部材の少なくとも１個の開口を貫通する、自動車用のエアバッグ用固定装置に関する。   The present invention relates to a fixing device for fixing an airbag to a vehicle, and in particular, a gas generator for an airbag for an automobile is fixed by means of at least one fixing bolt and a nut screwed to the fixing bolt. The bolt is for a gas generator and relates to a fixing device for an airbag for an automobile, which passes through at least one opening of a holding member that mounts the airbag and fixes the airbag.

車のシートに固定されるエアバック・モジュールにおいて、シート構造体の部材としてのポストの壁を貫通し、ナットにねじ込まれ固定される取り付け用ボルトが、ガス生成器のハウジングに取り付けられるタイプの固定装置は、特許文献１に開示されている。車のシートでのこの適用においては、更に電気的に動作／制御される構成部品（例えばリトラクター、シートベルトテンショナー等）が配置され、一体化されたシート構造体に取り付けられる。このようなエアバック・モジュール用の公知の構造体においては、十分に強い電流がガス生成器に流れ、シート構造体とそれに取り付けられるガス生成器の固定ボルトとの間に発弧（火花が飛ぶこと）メカニズムが形成され、ガス生成器による誤ったガス放出を必要な精度で阻止することが出来ないという問題が発生する。誤ってガスが放出されるというこの種の事故は、車の搭乗者に対し重大な結果を引き起こす。   In an air bag module fixed to a car seat, a fixing bolt that passes through the wall of a post as a member of a seat structure and is screwed into a nut and fixed to a housing of a gas generator The apparatus is disclosed in Patent Document 1. In this application in car seats, further electrically actuated / controlled components (eg retractors, seat belt tensioners, etc.) are arranged and attached to the integrated seat structure. In such a known structure for an air bag module, a sufficiently strong current flows through the gas generator, and an arc (sparks fly) is generated between the seat structure and the fixing bolt of the gas generator attached thereto. A) a mechanism is formed, and there arises a problem that erroneous gas release by the gas generator cannot be prevented with a necessary accuracy. This type of accident, in which gas is accidentally released, has serious consequences for car occupants.

米国特許５８０３４８６Ａ号明細書US Pat. No. 5,803,486A

このため、本発明の目的は、誤ったガス放出を阻止するような固定装置を提供することである。
上記の目的は、本発明の好ましい実施形態とその変形例を含む特許請求の範囲に記載した内容によりその解決が図られる。 Therefore, an object of the present invention is to provide a fixing device that prevents erroneous gas release.
The above object can be solved by the contents described in the scope of claims including preferred embodiments of the present invention and modifications thereof.

本発明の基本的アイデアにおいては、本発明は、ガス生成器と自動車部品との間に電気的絶縁（以下、単に絶縁と称する）を提供する。本発明の好ましい方法においては、本発明の構成により、発生する電流がガス生成器に到達するのを阻止し、固定装置間の発弧メカニズムの形成を阻止する。   In the basic idea of the present invention, the present invention provides electrical insulation (hereinafter simply referred to as insulation) between the gas generator and the automotive part. In a preferred method of the present invention, the configuration of the present invention prevents the generated current from reaching the gas generator and prevents the formation of an arcing mechanism between the fixing devices.

本発明の一実施形態において、シェルは、絶縁性材料で形成され、保持部材の開口に少なくとも１個の肩部で係合し、固定ボルトと保持部材の開口端部との間の絶縁を提供し、固定ボルトを包囲するが、このシェルが、ガス生成器と保持部材との間の接触領域に少なくとも跨るように伸びる。絶縁材料製のブッシングが固定ボルトにねじ込まれるナットとナットの坦持表面との間で保持部材上に配置される。ガス生成器と保持部材との間の接触表面を絶縁するシェルが、その肩部で保持装置の開口内を通過すると、固定ボルトも保持部材から絶縁される。ナットを保持部材から絶縁することは、それらの間に挿入されたブッシングにより行われる。   In one embodiment of the present invention, the shell is formed of an insulative material and engages at least one shoulder to the retention member opening to provide insulation between the securing bolt and the open end of the retention member. And surrounds the fixation bolt, but this shell extends at least across the contact area between the gas generator and the holding member. A bushing made of an insulating material is arranged on the holding member between the nut screwed into the fixing bolt and the carrying surface of the nut. When the shell that insulates the contact surface between the gas generator and the holding member passes through the opening of the holding device at its shoulder, the fixing bolt is also insulated from the holding member. Insulating the nut from the holding member is performed by a bushing inserted between them.

このため、更に本発明の一実施形態によれば、シェルの肩部は、ガス生成器から離れる方向に面する保持部材の外側上にフック状の半径方向突起部を形成する。更に好ましくは、フック状の突起部を有するシェルの肩部は、柔軟性を有し、保持部材の開口内に押し込まれた時に、自動車部品と柔軟に係合する。   Thus, according to an embodiment of the present invention, the shoulder of the shell forms a hook-shaped radial projection on the outside of the holding member facing away from the gas generator. More preferably, the shoulder portion of the shell having the hook-shaped protrusion has flexibility, and flexibly engages with the automobile part when being pushed into the opening of the holding member.

更に、本発明の一実施形態によれば、肩部の半径方向突起部は、ブッシングのサポートを構成する。別の構成として、ブッシングは、半径方向突起部に外部で係合し、その端部は、前記保持部材の全面上にある。ブッシングの内側表面は、突起部に係合し、突起部の外側表面は、互いに対応する傾斜表面を有する。   Furthermore, according to an embodiment of the present invention, the radial projection of the shoulder constitutes a support for the bushing. Alternatively, the bushing is externally engaged with the radial protrusion and its end is on the entire surface of the retaining member. The inner surface of the bushing engages the protrusion, and the outer surface of the protrusion has inclined surfaces that correspond to each other.

適宜のプラスチック材料が、電気絶縁の手段として使用される。   Any suitable plastic material is used as a means of electrical insulation.

静電気がエアバッグに現れても、本発明に採られた絶縁措置により、導電性の自動車部品に自動的に放電することはない。本発明の一実施形態によれば、化合物充填ゲーブルで固定ボルトと導電性自動車部品とを接続し、エアバッグ近傍の静電気も同様に排除される。   Even if static electricity appears in the airbag, the insulation measures taken by the present invention do not automatically discharge the conductive automobile parts. According to one embodiment of the present invention, the fixing bolt and the conductive automobile part are connected with the compound-filled gable, and static electricity in the vicinity of the airbag is similarly eliminated.

本発明の一実施形態によれば、エアバッグ・モジュールを固定する保持部材は、自動車シートの構造体に固定される。本発明は、一体化された保持部材を有するエアバッグ・モジュールが、自動車のシートの外側（例えば、計器パネルの近傍の導電性部品）に固定されるエアバッグの絶縁性搭載にも適用できる。更に、本発明は、必ずしも、保持部材を含むものに限定されるものでもない。ガス生成器又はそのハウジングの固定ボルトエアバッグ・モジュールを固定する自動車部品の開口に直接導かれる。この固定措置は、前述した特許文献１に開示されたように、固定ボルトにねじ込まれたナットにより行われる。   According to one embodiment of the present invention, the holding member that fixes the airbag module is fixed to the structure of the automobile seat. The present invention can also be applied to an insulating mounting of an airbag in which an airbag module having an integrated holding member is fixed to the outside of an automobile seat (for example, a conductive component in the vicinity of an instrument panel). Further, the present invention is not necessarily limited to the one including the holding member. Directed to the opening of the automotive part that secures the gas generator or its fixing bolt airbag module in its housing. This fixing measure is performed by a nut screwed into a fixing bolt as disclosed in Patent Document 1 described above.

図１のエアバック・モジュール１０は、２つの部品から構成される外側ハウジング組立体１１を有し、その一方の上に配置されたヒンジ付き接続部１４と、他方の上に配置されたスナップ接続部１２より一体に保持配置される。外側ハウジング組立体１１の一方には所定の破損予定点１３が具備され、この破損予定点１３はエアバック・モジュール１０内に配置されたエアバッグ１６の膨張圧により破壊される。その結果、外側ハウジング組立体１１の一方は、ヒンジ付き接続部１４を蝶番にして開く。   The airbag module 10 of FIG. 1 has an outer housing assembly 11 composed of two parts, a hinged connection 14 disposed on one of them and a snap connection disposed on the other. It is held and arranged integrally from the portion 12. One of the outer housing assemblies 11 is provided with a predetermined expected breakage point 13, which is destroyed by the inflation pressure of the airbag 16 disposed in the airbag module 10. As a result, one of the outer housing assemblies 11 opens with the hinged connection 14 as a hinge.

ガス生成器１５と折りたたまれた状態のエアバッグ１６とが、エアバック・モジュール１０内の内部に配置される。ガス生成器１５は、エアバック・モジュール１０の内側に伸びる保持部材１７上に取り付けられ、そこを貫通する固定ボルト１８とこの固定ボルト１８上にネジ止めされるナット２２とで固定される。保持部材１７は、エアバック・モジュール１０を超えて伸びて、その端部で搭載用フック２０と搭載用開口２１を有し、保持部材１７は、車両の部品例えば特許文献１に示されたシート構造体の部分に、適宜の固定部材の手段により取り付けられる。   The gas generator 15 and the folded airbag 16 are disposed inside the airbag module 10. The gas generator 15 is mounted on a holding member 17 that extends inside the airbag module 10, and is fixed by a fixing bolt 18 that passes through the holding member 17 and a nut 22 that is screwed onto the fixing bolt 18. The holding member 17 extends beyond the airbag module 10 and has a mounting hook 20 and a mounting opening 21 at its end, and the holding member 17 is a vehicle component such as a seat shown in Patent Document 1. It is attached to the structure part by means of an appropriate fixing member.

車両部品あるいはシート構造体とガス生成器との電気的接続を遮断（絶縁）し、保持部材１７とガス生成器１５用の固定装置（固定ボルト１８とナット２２から構成される）との間の発弧メカニズムを阻止するために、絶縁性（好ましくは適宜のプラスチック材料製）のシェル２３が、ガス生成器１５の着床領域内で保持部材１７に当たり、ガス生成器１５と保持部材１７との間に配置されシェル２３が、同様に固定ボルト１８を絶縁し、ナット２２と保持部材１７との間に配列されたブッシング２６により絶縁が補強される。   The electrical connection between the vehicle part or the seat structure and the gas generator is interrupted (insulated), and between the holding member 17 and the fixing device for the gas generator 15 (consisting of a fixing bolt 18 and a nut 22). In order to prevent the arcing mechanism, an insulating (preferably made of a suitable plastic material) shell 23 hits the holding member 17 in the landing area of the gas generator 15, and the gas generator 15 and the holding member 17 A shell 23 arranged in between also insulates the fixing bolt 18 and is reinforced by a bushing 26 arranged between the nut 22 and the holding member 17.

固定ボルト１８による固定装置の近傍の絶縁状態を図２に示す。同図において、シェル２３は、固定ボルト１８の周囲に肩部２４を有し、肩部２４は、保持部材１７とガス生成器１５との間に配置され、保持部材１７に形成された開口３０を貫通し、ガス生成器１５から離れる方向に面した側上でフック状態で保持部材１７に、外側に向いた半径方向突起部２５でもって、係合する。この構造により、開口３０の近傍で固定ボルト１８の方向に向いた保持部材１７の面は保護され、固定ボルト１８から絶縁され、その結果この領域で電気的接続は起こらない。   The insulation state in the vicinity of the fixing device by the fixing bolt 18 is shown in FIG. In the figure, the shell 23 has a shoulder portion 24 around the fixing bolt 18, and the shoulder portion 24 is disposed between the holding member 17 and the gas generator 15 and has an opening 30 formed in the holding member 17. Is engaged with the holding member 17 in a hooked state on the side facing away from the gas generator 15 with a radial projection 25 facing outward. With this structure, the surface of the holding member 17 facing the fixing bolt 18 in the vicinity of the opening 30 is protected and insulated from the fixing bolt 18, so that no electrical connection takes place in this region.

固定するために、ナット２２が固定ボルト１８にねじ込まれる際、絶縁材料製のブッシング２６がナット２２と保持部材１７との間に配置され、ナット２２はブッシング２６上でそれ自身を固定し、ナット２２と保持部材１７との間の電気的接続が阻止される。図２に示した実施形態においては、半径方向突起部２５に係合するブッシング２６の内面２８と半径方向突起部２５の外面２７とは、対向する傾斜面に対応する傾斜面を有するよう両方とも設計されている。   For fixing, when the nut 22 is screwed into the fixing bolt 18, a bushing 26 made of an insulating material is arranged between the nut 22 and the holding member 17, and the nut 22 fixes itself on the bushing 26. The electrical connection between 22 and the holding member 17 is prevented. In the embodiment shown in FIG. 2, the inner surface 28 of the bushing 26 that engages the radial protrusion 25 and the outer surface 27 of the radial protrusion 25 are both so as to have inclined surfaces corresponding to the opposed inclined surfaces. Designed.

シェル２３と肩部２４と半径方向突起部２５とは、シェル２３を保持部材１７に組み立てる間、シェル２３と保持部材１７との間で係合するスナップ結合ができるよう配列（構成）される。   The shell 23, the shoulder 24, and the radial protrusion 25 are arranged (configured) so that a snap coupling that engages between the shell 23 and the holding member 17 can be performed while the shell 23 is assembled to the holding member 17.

ガス生成器１５の静電気の蓄積を阻止するために、化合物を充填したケーブル３１が固定ボルト１８を導電性の自動車部品に接続し、自動車部品及び／又はそれに接続される保持部材１７とガス生成器１５との間の電気的絶縁が行われる。   In order to prevent accumulation of static electricity in the gas generator 15, a cable 31 filled with a compound connects the fixing bolt 18 to a conductive automobile part, and the automobile part and / or the holding member 17 connected thereto and the gas generator Electrical insulation with 15 is performed.

本明細書に開示した発明の目的、特許請求の範囲、要約書、図面等は、様々な実施形態あるいは変形例において、単独あるいは組み合わせて本発明の具体化するために必須なものである。   The object of the invention, claims, abstract, drawings, and the like disclosed in the present specification are indispensable for embodying the present invention alone or in combination in various embodiments or modifications.
